Description

Technical Field

[0001] This utility model relates to the technical field of twisting machines, and more particularly to a horizontal double-reverse twisting machine. Background Technology

[0002] The horizontal double untwisting stranding machine is a stranding device specifically designed for high-frequency data cables. Its core function is to solve the torsional stress problem of the cable during stranding through a pre-untwisting mechanism, ensuring the structural stability and transmission performance of the insulated core wires. The equipment adopts a horizontal structure, integrating untwisting and stranding functions, and is equipped with a heating plate to prevent the rubber sheath from falling off. At the same time, a motor-driven cooling fan is used to maintain the internal temperature and improve the stability of the equipment.

[0003] Chinese Patent No. CN212322731U discloses a horizontal double-reverse twisting machine, including a twisting machine, a heating plate, a motor, a cooling fan, an inspection door, and a hinge. The twisting machine has an inner cavity in the middle, and an inlet and an outlet are respectively provided at the left and right ends of the twisting machine. The heating plate is installed at the top and bottom of the inner cavity and is connected to a power source. The motor is installed at the top of the twisting machine, and the output end of the motor passes through the twisting machine and is connected to the top of the cooling fan. The cooling fan is located in the inner cavity. The front end of the twisting machine has two sets of doors that are slidably connected to the twisting machine. The front end of the first handle has a first handle. The rear end of the twisting machine has an inspection port. The inspection door is rotatably connected to the rear end of the twisting machine via a hinge to cover the inspection port. The front end of the inspection door has a second handle.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: the existing horizontal double-reverse twisting machine cannot regulate the internal temperature during use. When the twisting machine temperature is low, the cable is prone to breakage, which affects the twisting quality. When the twisting machine temperature is high, it is easy for the equipment to overheat and cause damage. At the same time, dust is easy to accumulate at the heat dissipation vent, affecting the heat dissipation effect. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that the internal temperature of the twisting machine cannot be adjusted and the dust at the heat dissipation vents cannot be cleaned, and to propose a horizontal double-reverse twisting machine.

[0006] The technical solution of this utility model is as follows: A horizontal double-reverse twisting machine, comprising a twisting machine body and a heater disposed inside the twisting machine body; further comprising:

[0007] A heat dissipation adjustment mechanism is located on the top of the twisting machine body. It is used to generate heat dissipation airflow and adjust the airflow size according to the internal temperature of the twisting machine body.

[0008] The fan blades are mounted on the heat dissipation adjustment mechanism. A connecting shaft is located on the inner side of the fan blades, and a spur gear is located at the end of the connecting shaft. A rack meshes with the side of the spur gear, and a connecting plate is located at the bottom of the rack. Four fan blades are arranged in a ring around the connecting plate. The heat dissipation adjustment mechanism drives the fan blades to rotate rapidly, thereby generating airflow. The airflow dissipates heat from the inside of the twisting machine body. When the temperature inside the twisting machine body changes, the heat dissipation adjustment mechanism drives the connecting plate to move up and down. The connecting plate drives the rack to move, and the rack drives the spur gear to rotate. The spur gear drives the fan blades to deflect through the connecting shaft, thereby adjusting the tilt angle of the fan blades. The greater the tilt angle between the fan blades and the axis, the greater the heat dissipation airflow, and vice versa.

[0009] And a dust removal mechanism, which is set on the heat dissipation regulating mechanism, is used to circulate and remove dust from the heat dissipation regulating mechanism and collect the dust at the edge by sweeping out the device.

[0010] Preferably, it also includes a winding assembly, which includes a second motor, a second shaft, and a support rod;

[0011] The support rod is located on the outside of the winch body, the second motor is located at the end of the support rod away from the winch body, the second rotating shaft is located at the output end of the second motor, a connecting piece is located on the outside of the second rotating shaft, and a take-up roller is located at the end of the connecting piece away from the second rotating shaft.

[0012] Preferably, the heat dissipation adjustment mechanism includes a heat dissipation pipe, a dustproof plate, an adjustment component, and a blower component;

[0013] The heat dissipation pipe is located on the top of the twisting machine body, and the dustproof plate is located inside the heat dissipation pipe;

[0014] The air blowing component is located inside the dustproof plate and is used to blow air to the inside of the twisting machine body for heat dissipation.

[0015] The adjustment component is located at the bottom of the blower assembly and is used to adjust the airflow of the blower assembly.

[0016] Preferably, the blower assembly includes a motor, a shaft, and a mounting plate;

[0017] One motor is located inside the dustproof plate, one rotating shaft is located at the output end of the motor, and a mounting plate is located at the bottom of the rotating shaft. The outer side of the connecting shaft and the mounting plate are rotatably connected.

[0018] Preferably, the adjustment component includes a fixed block and a sliding disk;

[0019] The fixing block is located at the bottom of the mounting plate, and the inner side of the fixing block is slidably connected to the outer side of the rack. The sliding plate is rotatably located at the bottom of the connecting plate. A lifting rod is located at the bottom of the sliding plate, a temperature sensing element is located at the bottom of the lifting rod, and a fixing frame is located at the bottom of the temperature sensing element. The end of the fixing frame is connected to the inner side of the twisting machine body.

[0020] Preferably, the dust removal mechanism includes a connecting shaft, a rotating plate, a cleaning rod, and an insert rod;

[0021] The second connecting shaft is mounted on the first rotating shaft. The rotating plate is located at the end of the second connecting shaft away from the first rotating shaft. The cleaning rod is rotatably mounted on the outside of the first rotating shaft. The insertion rod is slidably mounted on the inside of the rotating plate. A spring is mounted on the outside of the insertion rod. A fixing member is mounted at the end of the spring. The end of the fixing member away from the insertion rod is connected to the outside of the cleaning rod. A dust collection box is mounted on the outside of the heat dissipation pipe.

[0022] Compared with the prior art, this utility model has the following beneficial technical effects: By setting up a dust removal mechanism and a heat dissipation adjustment mechanism, when the rotating plate and the cleaning rod are connected together, the motor can drive the cleaning rod to rotate, thereby cleaning the dust on the dustproof plate. This prevents dust from accumulating at the heat dissipation vents, ensuring unobstructed heat dissipation channels and improving heat dissipation efficiency. When not in use, the connection between the rotating plate and the cleaning rod can be disconnected, thus not affecting the increased load on the motor and reducing consumption. The temperature sensing element senses the temperature inside the machine body and adjusts the angle between the fan blades and the shaft, thereby adjusting the airflow size blown by the fan blades, increasing the heat dissipation area, and enabling the equipment to achieve better heat dissipation in a shorter time. This helps the equipment maintain a stable temperature during long-term operation, better controls the operating temperature, reduces the risk of overheating, avoids equipment failure or damage due to overheating, and improves equipment stability.

[0029] Example 1

[0030] like Figures 1-5 As shown, the present invention proposes a horizontal double-reverse twisting machine, including a twisting machine body 1, a heater 5 disposed inside the twisting machine body 1, a heat dissipation adjustment mechanism, a fan blade 310, and a dust removal mechanism. The twisting machine body 1 has a feed inlet on the front side and a discharge outlet on the rear side for passing cables. The heater 5 is located at the upper and lower ends of the feed inlet for heating the inside of the twisting machine body 1.

[0031] The heat dissipation adjustment mechanism is located on the top of the twisting machine body 1 to generate heat dissipation airflow and adjust the airflow size according to the internal temperature of the twisting machine body 1.

[0032] The fan blades 310 are mounted on the heat dissipation adjustment mechanism. A connecting shaft 309 is mounted on the inner side of the fan blades 310. A spur gear 311 is mounted at the end of the connecting shaft 309. A rack 312 meshes with the side of the spur gear 311. A connecting disk 314 is mounted at the bottom of the rack 312. Four fan blades 310 are arranged in a ring around the connecting disk 314. The heat dissipation adjustment mechanism drives the fan blades 310 to rotate rapidly, thereby generating airflow. The airflow dissipates heat from the inside of the twisting machine body 1. When the temperature inside the twisting machine body 1 changes, the heat dissipation adjustment mechanism drives the connecting disk 314 to move up and down. The connecting disk 314 drives the rack 312 to move. The rack 312 drives the spur gear 311 to rotate. The spur gear 311 drives the fan blades 310 to deflect through the connecting shaft 309, thereby adjusting the tilt angle of the fan blades 310. The larger the tilt angle between the fan blades 310 and the axis, the greater the heat dissipation airflow, and vice versa.

[0033] The dust removal mechanism is installed on the heat dissipation regulating mechanism and is used to circulate and remove dust from the heat dissipation regulating mechanism and collect the dust at the edges by the sweeping device.

[0034] The winding assembly includes a second motor 202, a second shaft 203, and a support rod 201;

[0035] A support rod 201 is located on the outside of the twisting machine body 1. A second motor 202 is located at the end of the support rod 201 away from the twisting machine body 1. A second rotating shaft 203 is located at the output end of the second motor 202. A connector 204 is located on the outside of the second rotating shaft 203. A take-up roller 205 is located at the end of the connector 204 away from the second rotating shaft 203. The end of the twisted cable is fixed on the take-up roller 205. When the second motor 202 is started, the second motor 202 drives the second rotating shaft 203 to rotate. The second rotating shaft 203 drives the take-up roller 205 to rotate through the connector 204, thereby winding up the twisted cable.

[0036] The heat dissipation adjustment mechanism includes a heat dissipation pipe 301, a dustproof plate 302, an adjustment component, and a blowing component. The heat dissipation pipe 301 is located on the top of the twisting machine body 1, and the dustproof plate 302 is located inside the heat dissipation pipe 301. The blowing component is located inside the dustproof plate 302 and is used to blow air to dissipate heat from the inside of the twisting machine body 1. The adjustment component is located at the bottom of the blowing component and is used to adjust the airflow of the blowing component. The blowing component includes a motor 303, a rotating shaft 304, and a mounting plate 305. The motor 303 is located inside the dustproof plate 302, the rotating shaft 304 is located at the output end of the motor, and the mounting plate 305 is located at the bottom of the rotating shaft 304. The outer side of the connecting shaft 309 and the mounting plate 305 are rotatably connected. The adjustment assembly includes a fixed block 313 and a sliding disk 315. The fixed block 313 is disposed at the bottom of the mounting disk 305, and the inner side of the fixed block 313 is slidably connected to the outer side of the rack 312. The sliding disk 315 is rotatably disposed at the bottom of the connecting disk 314. A lifting rod 308 is disposed at the bottom of the sliding disk 315, a temperature sensing element 306 is disposed at the bottom of the lifting rod 308, a fixing frame 307 is disposed at the bottom of the temperature sensing element 306, and the end of the fixing frame 307 is connected to the inner side of the winch body 1. The temperature sensing element 306... The temperature inside the winch body 1 is sensed, driving the lifting rod 308 to move. The lifting rod 308 drives the sliding plate 315 and the connecting plate 314 to move. The connecting plate 314 drives the rack 312 to slide on the fixed block 313, thereby driving the spherical gear 311 to rotate. This changes the tilt angle between the fan blade 310 and the axis. When the tilt angle increases, the airflow increases and the heat dissipation effect is enhanced. When the tilt angle decreases, the airflow decreases and the heat dissipation effect is weakened. This stabilizes the temperature inside the winch body 1 within a certain range. When it is necessary to clean the dustproof plate 302.

[0037] Example 2

[0038] like Figures 3-5 As shown, this utility model proposes a horizontal double-reverse twisting machine. Compared with Embodiment 1, this embodiment details the structure of the dust removal mechanism.

[0039] The dust removal mechanism includes a second connecting shaft 401, a rotating plate 402, a cleaning rod 403, and an insert rod 404. The second connecting shaft 401 is mounted on the first rotating shaft 304. The rotating plate 402 is located at the end of the second connecting shaft 401 away from the first rotating shaft 304. The cleaning rod 403 is rotatably mounted on the outside of the first rotating shaft 304. The insert rod 404 is slidably mounted on the inside of the rotating plate 402. A spring 406 is mounted on the outside of the insert rod 404. A fixing member 405 is mounted at the end of the spring 406. The end of the fixing member 405 away from the insert rod 404 is connected to the outside of the cleaning rod 403. A dust collection box 407 is mounted on the outside of the heat dissipation pipe 301. The dust collection box 407 is arranged in a ring around the heat dissipation pipe 301. Four, when the rotating shaft 304 rotates, it drives the connecting shaft 401 to rotate, and the connecting shaft 401 drives the rotating plate 402 to rotate. When the cleaning rod 403 is needed, pull the insert rod 404 to disengage it from the cleaning rod 403. Then, rotate the rotating plate 402 to a position directly opposite the insert rod 404 and release the insert rod 404. The insert rod 404 is inserted into the notch on the rotating plate 402 and then into the cleaning rod 403, thus connecting the rotating plate 402 and the cleaning rod 403 together. At this time, the rotating shaft 304 can drive the cleaning rod 403 to rotate. When the cleaning rod 403 rotates, it drives the dust on the dustproof plate 302 to be cleaned. The garbage at the edge is pushed into the dust collection box 407 for collection.

[0040] In summary, when using this utility model, the heater 5 is activated to heat the twisting machine body 1. After heating to the preset temperature, the cable is inserted into the device through the feed port for twisting. After the twisting is completed, the cable comes out through the discharge port. Then, the end of the cable is fixed on the take-up roller 205. The second motor 202 is activated, which drives the second shaft 203 to rotate. The second shaft 203 drives the take-up roller 205 to rotate through the connector 204, thereby winding up the twisted cable. The first motor 303 is activated, which drives the fan blade 310 to rotate through the first shaft 304 and the mounting plate 305. The fan blade 310 generates airflow to dissipate heat from the inside of the twisting machine body 1 and quickly mixes the hot airflow inside evenly. The internal temperature of the twisting machine body 1 will change during use. At this time, the temperature sensing element 306 senses the internal temperature of the twisting machine body 1 and drives the lifting rod 308 to move. When the lifting rod 308 moves, it drives the sliding plate 315 and the connecting plate 314 to move. The connecting plate 314 drives the rack 312 to slide on the fixed block 313, thereby driving the spherical gear 311 to rotate. This changes the inclination angle between the fan blade 310 and the axis, stabilizing the temperature inside the winch body 1 within a certain range. When it is necessary to clean the dustproof plate 302, pull the insert rod 404 to disengage it from the cleaning rod 403. Then, rotate the rotating plate 402 to a position directly opposite the insert rod 404 and release the insert rod 404. The insert rod 404 is inserted into the notch on the rotating plate 402 and then into the cleaning rod 403, thus connecting the rotating plate 402 and the cleaning rod 403 together. At this time, the rotating shaft 304 can drive the cleaning rod 403 to rotate. When the cleaning rod 403 rotates, it drives the dust on the dustproof plate 302 to be cleaned. The garbage at the edge is pushed into the dust collection box 407 for collection.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
